Democrats Push Immigration Changes as Senate Prepares for Markwayne Mullin’s DHS Confirmation

(UNITED STATES) — Senate Democrats are using Senator Markwayne Mullin’s confirmation hearing for Secretary of Homeland Security to press for new limits on immigration enforcement as a partial DHS funding shutdown stretches into its second month.

The fight has tied Senator Markwayne Mullin’s DHS confirmation to a broader clash over how the department should police immigration, who should lead it through a funding lapse, and whether Congress should impose new restraints on federal agents before reopening the department in full.

Senator Gary Peters, Ranking Member of the Senate Homeland Security Committee, cast the hearing as a test of crisis leadership on March 18, 2026. “How the Homeland Security Secretary responds to a crisis sends signals to everyone. It’s not the role of the secretary to be a cable news commentator in the wake of a crisis. [Mullin] will face grilling. on his readiness to take on such a significant role at such a critical time.”

That standoff is unfolding during a partial DHS funding shutdown that began on February 14, 2026. Democrats are withholding support for a funding bill unless it includes what they describe as guardrails on ICE and CBP conduct, while Republicans are pushing for quick action to restore operations and install new leadership.

The White House has framed the nomination around execution of President Trump’s priorities. White House Spokeswoman Abigail Jackson said on March 17, 2026, “Whether it be protecting the homeland from bad actors, stopping dangerous drugs. or removing the worst-of-the-worst criminal illegal aliens, Senator Mullin will work tirelessly to implement the President’s agenda.”

DHS has focused its public message on the operational effects of the funding lapse, especially for travelers and front-line workers. In a March 17, 2026 statement, the department said, “SPRING BREAK UNDER SIEGE: Democrats’ Reckless DHS Shutdown is Forcing TSA Officers to Work Without Pay and Holding American Travelers Hostage.”

Senate Minority Leader Chuck Schumer has argued that replacing one official will not address deeper problems inside the department’s enforcement arms. On March 11, 2026, Schumer said, “The rot in ICE is deep. It’s not one person—it goes deep within it. And what we need is not changing the personnel, but changing the law.”

At the center of the dispute is a package of enforcement changes Democratic leaders Hakeem Jeffries and Schumer want attached to any measure to reopen funding. Their demands include a requirement that agents obtain warrants signed by a judge before entering private property.

They also want a total ban on masks worn by deportation officers during operations. Another proposal would require mandatory body cameras and clear identification on all uniforms.

A further condition would bar enforcement actions at hospitals, schools, churches, and polling places. Democrats are also seeking new, stricter national use-of-force standards.

Those demands have turned the confirmation process into more than a review of Mullin’s qualifications. They have made the hearing a proxy battle over how immigration agents conduct operations, how much discretion department leaders should have, and whether Congress should use the budget to force policy change.

The pressure campaign followed the January 2026 shooting deaths of two U.S. citizens, Renee Good and Alex Pretti, during an enforcement operation in Minneapolis. That episode sharpened scrutiny of accountability, oversight and command decisions inside DHS, and it now hangs over the confirmation fight.

Mullin was nominated to replace Kristi Noem, who was reassigned to “Special Envoy for the Shield of the Americas” after facing intense criticism for her leadership and the Minneapolis incident. His nomination landed in a department already under pressure from a funding lapse, political infighting and questions about how enforcement operations are supervised.

Democrats have used that sequence of events to argue that the next Homeland Security secretary cannot simply promise tougher enforcement or smoother management. They want binding restrictions written into law before they help reopen the department.

Republicans have answered that the department needs confirmed leadership immediately and that a prolonged vacancy will deepen operational strain. Senate Majority Whip John Barrasso has called the Democratic demands “unrealistic” and urged a quick confirmation to “restore order.”

That split has made the partial DHS funding shutdown a bargaining tool in the wider immigration debate. One side is arguing for fast restoration of departmental stability; the other is using the lapse to force structural changes in how ICE and CBP operate.

The stakes extend well beyond Capitol Hill. At major airports including Atlanta and Houston, security wait times have reached three hours as TSA staffing shortages worsen during the lapse.

More than 100,000 DHS employees are working without pay. The strain has been especially visible at airport checkpoints, where more than 300 TSA agents have resigned since the shutdown began, citing financial exhaustion.

DHS has pointed to those pressures as evidence that Congress should move quickly to restore money and confirm leadership. Democrats, meanwhile, have said operational pain does not erase the need for legal restraints on enforcement practices.

The funding lapse has also reached disaster response. FEMA’s Disaster Relief Fund is at a “critical” level with only $5 billion remaining, forcing the agency to pause long-term rebuilding projects so it can preserve funds for immediate life-saving emergencies.

That has added another layer to the argument Peters raised about readiness. A Homeland Security secretary oversees not only immigration enforcement and airport security, but also disaster response at a moment when the department is juggling reduced funds, workforce stress and political confrontation.

Immigrant communities are feeling the effects in a different way. The “mass deportation” agenda has stalled because of funding problems, but uncertainty around enforcement priorities remains high as Democrats and Republicans battle over what rules should govern future operations.

Costs have also risen. USCIS implemented a premium processing fee hike effective March 1, 2026, adding to the financial burden on families and employers already facing delays, legal uncertainty and shifting priorities during the shutdown.

That combination of stalled enforcement, new proposed guardrails and higher immigration processing costs has widened the scope of the fight. What began as a confirmation battle has become a broader dispute over the shape of immigration policy under a partially funded department.

For Democrats, the argument is that reopening DHS without legal changes would amount to restoring the status quo after Minneapolis. Schumer’s position has been that personnel changes alone cannot fix what he described as deeper institutional problems.

For Republicans and the White House, the case is that DHS cannot function properly through a prolonged funding lapse and leadership vacuum. Jackson’s statement made clear that the administration sees Mullin as the person who would carry out the president’s enforcement agenda once confirmed.

The political calculation on both sides is evident. Democrats are trying to convert leverage from the partial DHS funding shutdown into statutory limits on agents’ conduct. Republicans are trying to make the cost of delay — long lines, unpaid workers and strained emergency funds — outweigh demands for reform.

Whether either side yields may shape not only Mullin’s prospects but also the department he would inherit. If he is confirmed without policy concessions, he would take charge of a department that has already become a central battleground over immigration enforcement. If Democrats win some of their conditions, the next secretary would begin under tighter legal constraints than recent predecessors.

For now, the confirmation contest continues to unfold alongside a funding lapse that touches travelers, disaster programs, federal workers and immigrant families at the same time. The longer it lasts, the more difficult it becomes to separate the question of who should lead DHS from the fight over what DHS should be allowed to do.

Readers tracking shifts in the nomination, the shutdown and immigration policy can verify updates through the DHS Press Office, the USCIS Newsroom, the Senate Committee on Homeland Security, and the White House nominations page. Those channels are likely to move quickly as the Senate weighs Senator Markwayne Mullin, Democrats press their immigration demands, and the partial DHS funding shutdown continues to test the department’s operations.
